D = Diameter of supply hose from vacuum generator (mm)
n = number of distributor hose
d = diameter of distributor hose (mm)
A = area of hose (mm2)
Example 1
How to calculate hose for distributor branch with main ID D = 10 mm
number of hose n = 4
d = D/(√n)
= 10/(√4)
= 5 mm
hose ID for distributor d= 5 mm
Example 2
How to calculate hose ID main supply
number of hose = 4
hose ID for distributor d= 5 mm
A = (π d^2/4)* n
= (π 5^2/4)* 4
= 78.56 mm2
A = π D^2/4
D = √(4*78.56)/π
= 10 mm
hose ID for main supply = 10 mm
